Great, its not verifying steam userid ticket, its this dumbass invalid steam userid ticket error now. This is happening everytime I try to connect to servers using source mods or hldm:s. This is so fucking annoying.

You chose "Change User..." in the Steam drop down menu? If you close Steam it doesn't Log you off.

Here's another method of fixing this

Code:

Completely exit from the Steam client.
Go to C:\Program Files\Steam (or the Steam directory that was specified during installation).
Locate ClientRegistry.blob and rename this file to ClientRegistryOld.blob.
Restart Steam to allow the file to be recreated.
Test the issue once more.
